ADJUSTABLE UTILITY BAG William W. Kurzrock, Chicago, Ill. ApplicationJuly 21, 1958, Serial No. 749,795 1 Claim. oi. 1so-1.7

My invention relates to new and useful improvements in an adjustableutility bag and has for its principal object a structure which providesa primary bag or receptacle and a secondary bag or receptacle attachedthereto and adapted to provide separate receptacles.

Another object of my invention is in the provision in a device of thischaracter of a structure which provides a sightly bag of commodiousdimensions adapted to be readily converted into a relatively small andcompact bag which is attractive and easy to carry.

Yet another object of my invention is the provision in a device of thischaracter of a bag which is economical to manufacture and simple to use.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings showing the preferred form of construction, and in which:

Fig. 1 is a front elevational view of my utility bag in its extendedcondition;

Fig. 2 is a rear elevational view of my utility bag folded into itssmallest condition and showing indotted lines, its previous size; V

Fig. 3 is a rear elevational view of my utility bag similar to Fig. 1;

Fig. 4 is a rear elevational view showing the bag folded into its firstsmall size;

Fig. 5 is a rear elevational view showing my utility bag in its secondfolded size;

Fig. 6 is a rear elevational view showing my utility bag shown in itsnext smallest size; and

Fig. 7 is a rear elevational view of a modified fold showing a differentsize bag over that of Fig. 4.

My invention provides a comprehensive as well as utilitarian andattractive bag receptacle which can be readily adjusted to six ditferentsizes by means of strategically folding and fastening certain ends inpredetermined positions.

Referring to Fig. 1, I show a receptacle or bag 10 comprising a frontpanel 11 and a rear panel 12. These panels may be stitched togetheralong corresponding edges thereof in a manner to provide an open top ormouth portion. It is contemplated by me that my bag maybe made of anyflexible and foldable material or may be made of a pliable plastic inwhich case the certain cor- States Patent i wardly so as to cover theupper portions of flaps 28 and i responding edges would he heat sealed.Under the lat- On the front panel 11, I connectin any suitable manner apanel 14 which is also of, a trapezoidal form. This panel 14 provides asecondary compartment which is adapted to beclosed by a flap 15carriedby the uppergv free edge of the front panel 11. This flap 15 maybe,

closed by a suitable snap fastener. 16 as viewed in Fig.1. Referring toFig. 3, I illustrate suitable snap fasteners 17 and 18 in the lowercorners thereof. whel'ljlhe bag is converted to its next succeedingsmaller size, these fasteners 17 and 18 are adapted to connect tofasteners- 19 and 2t) fastened at predetermined 'pointson the rear,

panel 12; When the corners are folded, the-bag will -assume the shapeillustrated in Fig. 4. V

The rear panel 12 provides corresponding oppositely disposed fasteners21, 22, 23 and 24, the latter'two being situated adjacent the connectionof the handle 13 with the top open edge of the bag. The former fasteners21 and 22 are adapted to be located so that they will be exposed afterthe lowermost corners of the bag have been folded into the positionillustrated in Fig. 4. To reduce the bag to its next succeeding smallersize, the fasteners 21 and 22 are brought into fastening engagement withthe fasteners 23' and 24, while the bag is folded along line 25 asillustrated in Fig. 5. The bag so folded will again resume itstrapezoidal form. 1

As viewed in Figs. 5 and 6, the corners 26 and 27 are folded along linesA and B so that they create flaps 28 and 29. The flap 29 is adapted tobe folded into facial abutment with the receptacle While the flap 28 isfolded so as to overlie the flap 29 as shown in Fig. 6. The flaps 28 and29 are held in folded position by the fasteners 30 and 31 which areconnected to the front panel 11 but which are brought into facialabutment by the folding hereinbefore described.

A closure flap 32 which is carried by the'free edge of the rear panel12, may then be folded so as to overlie the panel 28. The flap 32 has afastener 33 which is adapted to cooperate with a like fastener 38 on theouter face of the flap 28 so as to secure the flaps 28 and 29 in theirfolded position.

In order to fold my utility bag into its smallest size, the flap 32 isopened and the uppermost'corners 34 and 35 of the bag as illustrated inFig. 6, are'then folded in- 29 in the position of the dotted lines asshown in Fig. 2.

The bottom portion 36 of the bag as viewed in Fig. 6 is then folded soas to cover the corners 34 and 35 as shown in Fig. 2. In such aposition, the flap 32 is brought over the bottom edge 36 and connectedto a fastener 37 which is provided by the front panel 11. In suchaffolded condition, the bag may be readily stored or carried in apocketbook or pocket of a garment.

Referring to Fig. 7, I illustrate a modified fold whereby the lowermostcorners of the bag are folded so that they are brought into facialrelation with the uppermost corners of the trapezoidal formed bag. Therethe. fasteners 17 and 18 are adapted to connect to the fasteners, 23 and24.

As fully described, my utility bag with its trapezoid shape can bereadily adjusted by means of the described folding-operations to sixdiflerent highly attractive sizes. In this principal design, I am using60. base angles and a 60 folding principle in order to accomplish themany sizes as he'reinbefore explained.

While I have illustrated and described the preferred form ofconstruction for carrying myv invention into ef feet, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, donot wish to be limited to the precise detailsof con,-

struction 'set 'forth, but desireto avail myself of such variations andmodifications as come within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to.protect by Letters Patent'is:

An adjustable utility bag made of flexible foldable material providing atrapezoidal shaped bag-like structure having a front wall and aback walldefining a compartment, handles connected 'to said front and back wallsintermediate the ends thereof and projecting outwardly from saidbag-like structure at the open end thereof, a

similar shaped wall member secured to said front wall adjacent the opentop-of saidJbag-like structure providing a secondary compartment, saidbag-like structure having its lower angled corners "foldable inwardlyupon the back wall of said bag-like structure onto a line mid-waybetween the top and bottom thereof where said bag-likestructureaisfurther folda'ble between its top and bottom so as to varythe size of the compartment defined by said front and back walls, eachof the new lastly formed angled corners foldable in the same manner uponthe front wall until the size of said newly formed bag-like structuresubstantially conforms to the size of the secondary compartment,fastening means on said walls for releasably securing each set of newlyformed corners in folded position, and cooperating fastening means forreleasably securing other positions of said bag-like structure in foldedrelation with respect to the open end of said compartment.
